摘要在探地雷达正演方法中, 射线追踪法只能获取了波的运动学特征, 时域有限差分法虽然能
得到波的动力学特征, 但是由于时空离散采用规则的结构化Yee 单元, 不能模拟复杂地质构造下 …

A nonconformal hybrid finite difference time domain (FDTD)/finite element time domain
(FETD) method was previously introduced, which implemented the hybridization through a …

A spectral-element time-domain (SETD) method is proposed to solve 3-D transient
electromagnetic problems based on Gauss-Lobatto-Legendre polynomials. It has the …

In this paper, we present an efficient model to study the coupling of an electromagnetic wave
with two electronic equipment enclosures. The first one has two large apertures, and the …

Computational electromagnetism deals with the mathematical modeling of electromagnetic
systems. Its purpose is not to establish physical theories, but to use these theories to …

The exponential time integration, ie, time integration which involves the matrix exponential,
is an attractive tool for time domain modeling involving Maxwell's equations. However, its …

Time-domain finite-element solutions of Maxwell's equations require the solution of a sparse
linear system involving the mass matrix at every time step. This process represents the bulk …

Abstract In the Ground-Penetrating Radar (GPR) forward modeling method, the ray-tracing
method can only obtain the kinematic characteristics of the wave. Although the finite …

Numerical integration of Maxwell's equations is often based on explicit methods accepting a
stability step size restriction. In literature evidence is given that there is also a need for …
